## What to fix first
- **No online booking link on the website.** (+13 points) There's only a phone number or WhatsApp, and agents can't use those yet. If you take bookings or orders through a platform, link to it from the site so agents can find it. Add an online appointment page. Guide: https://directindex.org/guides/book-direct-on-your-own-website
- **Structured data is incomplete.** (+7 points) Missing: address, telephone, opening hours. Guide: https://directindex.org/guides/structured-data-restaurant
- **No list of services and prices found.** (+7 points) Agents answer 'what do they treat and what does it cost?' from directories instead. Add a page that lists services and prices as text, and link to it from the homepage. Guide: https://directindex.org/guides/menu-pdf-ai
